Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors (127.44125L) feature a vented rotor design with straight vanes that promote efficient airflow to reduce heat buildup during braking. The cross-drilled and slotted surface pattern helps evacuate gases, dust, and water, improving brake pad contact and overall braking consistency. The coated hat finish provides corrosion resistance, which is essential for maintaining rotor integrity over time. These rotors have a floating disc mounting system that allows for thermal expansion, reducing the risk of warping under high-stress conditions.

With an outside diameter of 11.654 inches (296 mm) and a nominal thickness of 1.102 inches (28 mm), these rotors meet OEM specifications for the listed Lexus and Toyota models. The mounting bolt hole circle diameter is 114.3 mm (4.5 inches) with five lug holes, ensuring proper fitment. The center hole diameter measures 2.441 inches (62 mm), and the rotor weighs approximately 17 lbs (7.73 kg).
